Dingwall Castle is believed to have been established by Norse settlers in the area in the 11th century. During the Wars of Scottish Independence the castle was garrisoned by the forces of king Edward I of England. However it was later captured by Scottish forces for king Robert I of Scotland (Robert the Bruce) led by Uilleam II, Earl of Ross.
From the castle, the Earl of Ross (chief of Clan Ross) led the men of Ross to fight against the English at the Battle of Bannockburn in 1314. As a reward in 1321 King Robert granted Dingwall Castle with the town and lands of Dingwall to the Earl of Ross.
In 1370 a feud arose between William de Moravia, 5th Earl of Sutherland (chief of Clan Sutherland) and Aodh Mackay (chief of Clan Mackay). A meeting was arranged for them to meet at Dingwall Castle to resolve their issues. However Aodh Mackay and his son Donald Mackay were both murdered in the castle while they were asleep by Nicholas Sutherland, brother of the Earl of Sutherland.
In 1411 Domhnall of Islay, Lord of the Isles (chief of Clan Donald) captured Dingwall Castle as part of his attempt to seize the title of the Earldom of Ross. This took place shortly before the Battle of Harlaw. In 1438 the next successive Clan Donald chief, Alexander of Islay, Earl of Ross was officially recognised as the Earl of Ross and took up his residence at Dingwall Castle. His son, John of Islay, Earl of Ross was not as successful; the Earldom of Ross was confiscated from him and the castle became a royal possession once more in 1475. John Munro, 11th Baron of Foulis was then made governor of the castle, who in turn was succeeded by Andrew Munro, 2nd of Milntown. The next governor in 1488 was Sir James Dunbar.
In 1507 Andrew Stewart, Bishop of Caithness carried out improvements after the castle had been assaulted by the MacDonalds and Mackenzies. The Crown abandoned Dingwall Castle in about 1600 and it eventually fell into a ruin. The castle ceased to be maintained after the death of king James VI of Scotland in 1625. It was used as a quarry until 1817 when it was finally levelled and only a few fragments remain.
A tunnel still exists that runs from the site of Dingwall Castle to the basement of nearby Tulloch Castle. The tunnel has now collapsed, but it is possible to view this passageway through an air vent on the front lawn of Tulloch Castle's grounds.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
